That vid is absolute proof that fanofall was right when she said that Lex has chemistry with every object and human in his view, with the exception of his female love interests. Because after seeing that vid, I think a talented writer could probably believably slash Lex with a towel.

Lex appears to be thinking "Oh, yes, delicious" all the time. Whereas Clark appears to be thinking it only when he looks at Lex. No wonder the girls get forgotten in this show.
